An assembly and method for end-to-side anastomosis to an anatomical conduit is disclosed. The system and method are particularly useful in coupling an LVAD pump to an aorta. The assembly and method include using a tubular graft member having a distal flange section that conforms to and engages an abluminal wall surface of the aorta, an affixation component having a tubular proximal section and a distal flange section that is configured to conform to and engage with a luminal wall surface of the aorta and has a plurality of receiver openings passing through the distal flange section, and a plurality of anchoring components configured to pass through the distal flange section of the graft component, through the wall of the aorta or other major vessel, an engage with the receiver openings of the distal flange section of the affixation component to exert an axially compressive force there between and create a hemostatic seal around an opening formed in the wall of the aorta or major vessel that allows blood or other fluid to pass into and through the assembly and into the aorta or other anatomical conduit.
An assembly configured for end-to-side anastomosis, comprising, in combination a graft component having a tubular proximal section and a distal flange section, an affixation component comprising a diametrically expandable proximal tubular section and a diametrically expandable distal flange section, the diametrically expandable distal flange section comprising a plurality of radially extending strut members and at least one circumferential strut member connecting each of the plurality of radially extending strut members, wherein the diametrically expandable distal flange section is configured to conform to a luminal wall surface of an anatomic passageway;
An end-to-side anastomosis assembly, comprising, in combination a graft having a tubular proximal section and a distal flange section, a stent configured to be placed within a lumen of a blood vessel and conform to a luminal wall surface of the blood vessel, the stent having an annular opening in a wall thereof and a plurality of eyelet members each having a receiver opening arrayed about the annular opening;
An assembly configured for end-to-side anastomosis, comprising, in combination a graft component having a tubular proximal graft section and a distal flange graft section, an affixation component comprising a diametrically expandable lattice structure defining a proximal tubular affixation section and a distal flange affixation section, the distal flange affixation section having a plurality of eyelets having receiver openings arrayed about a circumference thereof and is configured to conform to a luminal wall surface of an anatomic passageway;
